A method of taking out upper layer solvent from de-laminating solvent, step includes
1) liquid level of the first liquid is measured, concrete operations are that the first liquid to be measured is added in capacity cup 1, start phase
Motor is answered, the rim of a cup of capacity cup 1 will be placed in into the nozzle of sample outlet pipe 8, starting suction pump 21, which is rotated forward, (herein, takes out
It is to realize sample introduction into sample outlet pipe 8 that sucking pump 21, which rotates forward, and rotating backward is to realize out sample into sample outlet pipe 8), pass in and out sample
Pipe 8 starts to aspirate air.
It moves down into sample outlet pipe 8 or moves up capacity cup 1, so that the liquid level of the first liquid is moved closer into the nozzle of sample outlet pipe 8,
After liquid level sensor 9 has detected that liquid enters into sample outlet pipe 8, stop to the movement into sample outlet pipe 8 or capacity cup 1, and root
The absolute altitude of liquid level is calculated according to movement speed and traveling time.That is, being located at capacity cup 1 from the nozzle into sample outlet pipe 8
Start timing when rim of a cup, start simultaneously at and be moved into and out sample pipe 8 or capacity cup 1, to liquid level sensor 9 detected liquid enter into
Timing terminates when sample outlet pipe 8, and this period is traveling time, and movement speed is to be manually set, and traveling time is multiplied by mobile speed
Degree obtains moving distance, this section of moving distance is 1 rim of a cup of capacity cup the distance between to the first liquid levels.
2) it is added second liquid in the first liquid, secondary clearing again after the first liquid is mixed with second liquid.With above-mentioned survey
The liquid level of the first liquid measured is benchmark face, will be placed in 1-5mm on datum-plane position into 8 nozzle of sample outlet pipe.
Theoretically, the datum level is the interface of the first liquid and second liquid, and disengaging sample nozzle is placed in datum-plane position
On 1-2mm can aspirate supernatant liquid, but be more not easy the sample being layered because the first liquid and second liquid boundary
Face is fuzzyyer, can properly increase and move up distance.Starting suction pump 21 is rotated forward, and aspirates supernatant liquid into sample outlet pipe 8
Into detection cup 27.
It will be placed in 1-5mm on the interface of two layers of solution into 8 nozzle of sample outlet pipe in the present embodiment, then from the bottom up
Upper solution is extracted, until liquid level is located at under the nozzle of sample outlet pipe 8, it can be ensured that into detection cup 27 liquid it is all on
Layer liquid.
Preferably, exclusion device, such as dehydration device, de-oiling dress can be set in the upstream of detection cup on second pipe
It sets.
3) cleaning step, including the cleaning to first pipe and to the cleaning of second pipe.Can before step 1) or
Person carries out cleaning step after step 2.
Embodiment 1
A method of the extraction and separation petroleum substance from water,
1) water (the first liquid) containing petroleum substance is placed in the capacity cup 1 in sample disc 2, mobile mechanical arm 6 will
The rim of a cup of capacity cup 1 is moved into the nozzle of sample outlet pipe 8, starting suction pump 21 is rotated forward, starts to aspirate into sample outlet pipe 8
Air, when by being moved downward to liquid level into the rim of a cup of the calm measuring cup 1 of sample outlet pipe 8, liquid is entered into sample outlet pipe 8, works as liquid level
Mechanical arm 6 stops decline when sensor 9 has detected liquid.
The timing since when the nozzle into sample outlet pipe 8 is located at capacity 1 rim of a cup of cup, while the correspondence motor of mechanical arm 6 is opened,
Drive mobile into sample outlet pipe 8 to liquid level direction, timing terminates when having detected that liquid enters into sample outlet pipe 8 to liquid level sensor 9,
Be denoted as traveling time, and remember that the decrease speed of mechanical arm 6 is movement speed, traveling time multiplied by movement speed obtain it is mobile away from
From being denoted as 1 rim of a cup of capacity cup the distance between to the first liquid levels.
2) start quantitative liquid pump 16 and extract certain volume just from the container (second liquid container 18) for accommodating n-hexane
Hexane (the second solution) starts agitating device to the mixed solution in capacity cup 1 by being injected into specimen cup 1 into sample outlet pipe 8
It is stirred extraction, is then allowed to stand layering.
After the completion of extraction, 1-2mm on datum-plane position is placed in into sample outlet pipe 8 and starts to sample, can guarantee to take out in this way
The n-hexane on upper layer after all layerings of the liquid taken.Organic phase hydrophobic filter is set in the upstream of detection cup on second pipe
One of device 20(dehydration device) and one of magnesium silicate column 25(deoiler), the moisture content in a small amount of n-hexane is by having
Machine phase hydrophobic filter 20 removes, and guarantees that all organic solvents of liquid entered in detection cup 27, magnesium silicate column 25 can be used for
Remove plant oil.Such design, which reduces, draws fluid into separation vessel progress secondary stratification bring pollution, reduces
Detergent line scavenging period and cleaning difficulty.
The present embodiment to the cleaning of first pipe is inverted by suction pump 21, and pure water is extracted from pure water cylinder 29 by the
One pipeline into sample outlet pipe 8 by being discharged, into capacity cup 1.Cleaning to second pipe is using quantitative liquid pump 16 from accommodating just
Organic solvent is extracted in the container 18 of hexane, diameter second pipe reaches waste liquid barrel 14.
